# Memory

The Memory module is designed to emulate the cognitive structures of memory, allowing AI agents to recall past experiences, learn from them, and make informed decisions. Just as humans rely on their memories to make sense of the world, AI agents utilize their memory structures to navigate the complexities of their digital environments.



Memory Structure:

Memory in AI agents can be organized hierarchically:

* **Short-Term Memory (STM):** Acting as the agent's immediate recall center, STM temporarily stores recent experiences and interactions, allowing for quick access and processing of fresh data.
* **Long-Term Memory (LTM):** This is the agent's knowledge base, a deep reservoir that holds onto past experiences, insights, and learnings. It provides a foundational backdrop against which the agent evaluates new information and makes decisions.
* **Network Memory (NM):** Beyond individual experiences, AI agents also tap into a shared memory pool, the Network Memory. This collective repository contains insights, patterns, and knowledge derived from the experiences of multiple agents within the network. It allows individual agents to benefit from the collective wisdom of the entire network, enhancing their decision-making capabilities and adaptability.



Memory Formats:

Different data formats can be used to store information:

* **Tabular:** Organizing data in tables, reminiscent of traditional databases. Q-tables used in Q-learning algorithms are a prime example.
* **Neural Representations:** Information is stored within the complex interplay of weights and biases in neural networks, facilitating intricate data representations.
* **Tree Structures:** A tiered format like decision trees that structures data hierarchically, aiding in organized decision-making.
* **Episodic:** Capturing specific events or instances, allowing agents to recall and reflect on particular experiences.



Memory Operations:

Various operations can be performed on memory:

* **Retrieve:** Agents can pull specific data or experiences from their memory for immediate use.
* **Store:** As agents interact and learn, they continually archive new data and experiences.
* **Update:** Memory is dynamic. Agents adjust and refine stored data based on new insights or feedback.
* **Prune:** To maintain efficiency, agents periodically remove outdated or less pertinent data, ensuring their memory remains streamlined and pertinent.
